I am probably going to get a new PSU along with an HD 4870, because my current PSU only has 1X6-pin, and its only 300W. What I want to do is get one that is <$50, probably a 500W, or 450. The dimensions of my current PSU are (Inches) 6x3.5x5.5, is that an ATX PSU or what? Also, it has one fan going out the back, and that's it. What brand is a good price, and still a strong PSU? I prefer Newegg, and I found this one:

Should i trust it? I know that a more expensive PSU is probably stronger, but I don't have more than $50 to spend. Also, my GPU will require 2x6-Pin.

Are you talking about the Corsair? But yeah use the inbuild one and the other converted from molex's.

It really isnt worth trying to go cheap on a PSU, wait your time and buy a good quality brand such as Corsair.
Although a cheap one may work perfectly for several years there's a greatly increased chance of it going up in smoke one day, possibly taking the rest of your setup with it.

Reply to FlamingGerbil

is Corsair the only good brand out there? I know that the ones that are put into computers like mine are probably not the best ones out there, and they work for years without problems, for the most part

seasonic, antec (not the basiq), ocz (decent), PC Power & Cooling are some others

Reply to mindless728

Antec, OCZ and Enermax are good, amongst others.
Like I said, they might work perfectly well, but that chance of them blowing up is much higher. Spending 20$ extra on a psu could potentially save you several hundred etc.

Reply to FlamingGerbil

ok, and what type of PSU is described by the dimensions I specified above? I see many PSU's with fans on top, mine doesn't have a hole in the top for a PSU fan, would it still work in my case?

Reply to stewartfan

If you're talking about the pictures like that psu you linked above, the wire covered fan points downwards, so essentially it's upside down there. Those dimensions look like a standard ATX.

Never had any personal experience with them, but from what I can gather, average quality.

Reply to FlamingGerbil

What about this one:

http://www.newegg.com/Product/Prod [...] 6817139008

are there any adapters that would allow me to use one of the connectors as a 6-Pin?

Reply to stewartfan

Indeed there are, you can get molex to 6-pin converters, which although gpu makers dont seem to like them, has worked fine for me using a GTX260 on an Enermax 485w which only had a single inbuild 6-pin.

Reply to FlamingGerbil

So, if I got the GPU along with this adapter:

is it possible that this:

GPU would work with my current setup?
Current PSU has 1x6-pin and at least one 4-Pin

Reply to stewartfan

I'm not 100% sure on that one, never tried 2x molex to 2x 6-pin conversion as the sole power supply for a card so I have no idea how stable that'll be.

Also I wouldnt try running a 4870 on a 300w power supply, that'd be a pretty bad idea right there.

Reply to FlamingGerbil

What I would do is use one of the built-in 6-Pins and one of the ones on the adapter.
If I tried it on the original PSU, could it ruin anything? If it works well, I really don't want to spend more on a new one

I personally wouldnt even try it, it'll bottleneck your card at the very best, also doubt that your 300w PSU has the neccesary Ampage on the +12v rail to run a 4870.

Reply to FlamingGerbil

yeah, i did that earlier, and i think it said something about 320 i think, but would it be safe to try it, and if it doesn't work, a new PSU will definitely be in the works.

Reply to stewartfan

It's honestly not worth even trying it, it'll be a waste of your time and money.

Reply to FlamingGerbil

well, no matter what, PSUs with 1x6-Pin are usually much cheaper, so I would be using the adapter most likely anyway, and it shouldn't waste much time. If i could get it to power the card so that I could use my computer for a week or so, I would have no complaints, and then get a new PSU, and if I'm really lucky (Doubtful, haha) then I wont need one, this is if my PSU is actually a really good 300W one, right?

Even if it's a really good 300w I cannot recommend it at all.
What brand is the 300w though, just out of interest.

It says Delta Electronics on it

Do not risk it then. Just use your old card until you can afford a decent PSU.

Reply to stewartfan

That should be viable, the efficiency is rather crap and I'm not too sure about the quality, but heyho, it's cheap at least. The Thermaltake support seems pretty active on the plus side.

Reply to FlamingGerbil

So this Corsair would work well, and last long? With a price of $30 after rebate, it can't be beat. The only problem is that I won't be buying it within the time of the rebate.
http://www.newegg.com/Product/Prod [...] 6817139008
Hopefully, I can get a good deal on another sale of one (with all of the Black Fridays Newegg is having, 10 or so). Is the fan for this one going to point downward into the case, or upward into the aluminum top of it?

A 300 watt Delta with a 6 pin pcie cable ?
Would you happen to have a model number ?

PS; the Corsair 400 is a much, much better choice than the Thermaltake 430,

@Delluser
On the bottom of the unit, it says
MODEL (some Chinese or something writing): DPS-300PB-3 A REV (more symbols) 00 F

I think this on is the closest one to what I have. I couldnt find the exact one on the site:

@FlamingGerbil
The case is already tight, would the factor of it pointing down contribute towards the overheating of my computer?

That's a 400 watt / 25 amp psu, I'd give the new card a shot, but would still be looking to upgrade.

I'm pretty sure its a 300, and the following pic is to show FlamingGrebil how my rig looks inside:

You might start suffering from heat with that new card, can only see a single 80mm exhaust fan there which will make everything run a little on the toasty side (or atleast it looks like an 80mm).
Although I dont think 4870's run too hot, so you should be alrite unless you decide to start overclocking, might want to turn the fan up a bit though.

Reply to FlamingGerbil

The general rule of thumb is a high quality 500 to 550 watt power supply with sufficient current (amps) on the 12 volt rail(s) can easily power a system with any single video card made. A high quality 700 to 750 watt power supply with sufficient current (amps) on the 12 volt rail(s) can power a system with two video cards operating in dual mode. There are a few exceptions like the new ATI Radeon HD 5XXX series cards which use less power due to their energy efficiency.

Corsair, PC Power & Cooling, and Seasonic are some of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Lately we've been seeing a few other brands offering some high quality units.

@FlamingGerbil
Do you recommend a simple free program to regulate my fan RPMs? I'm running Vista

@JohnnyLucky
With a 300W powering my system perfectly, won't this Corsair do me just fine?:

If just one ATI Radeon HD 4870 video card, then the Corsair CX400 with 30 amps on the 12 volt rail will do. The official recommendation is for a 450 watt power supply.

The ATI Radeon HD 4870 video cards require two 75 watt, 6 pin, PCI-e power connections. The Corsair CX400 and VX450 power supplies only come with one 6 pin PCI-epower cable. That's typical for low wattage psu's. That is not adisaster. I know the XFX version of the 4870 video card ships with a molex to 6 pin adapter. Many brands usually include a molex to 6 pin adapter just in case.

Here is a link to a power consumption chart from a Tom's Hardware review of the 4870:

http://www.tomshardware.com/review [...] 64-15.html

The blue color is the test system total power consumption while playing Test Drive Unlimited. It weighed in at 283 watts. Peak during a stress test would have been much higher.

Reply to JohnnyLucky

So, something similar to the Corsair, preferably higher wattage is what I should look for?

I was also planning to buy a Molex to 6-pin along with the purchase of the GPU/PSU as mentioned above

Nah that Corsairs wattage will be fine, you dont 'need' to go any higher then that, every graphics card manufacturer greatly inflate their stated power requirements on the box (possibly as a safety barrier), also the ampage on the +12v rail(s) is far more important.

@JohnnyLucky: My XFX GTX260 came with the molex adapter as well, which I found quite entertaining as in the manual it stated that you shouldnt use them to power the card.
Been using it for months now without any issue so not sure what they were on about there.

Reply to FlamingGerbil

FlamingGerbil - Sometimes there are interesting discussions here about whether or not it would be okay to use a molex to 6 pin adapter. It gets kind of crazy.

Reply to JohnnyLucky

I'd prefer not to personally, even though it's run perfectly fine so far splitting two molex's to power it seems a little bodged for my liking.
Should be getting a new Corsair 650 to sort that out though, with a nice headroom for some OC'ing and the like!

Reply to FlamingGerbil

Would it be better to use the in-build one along with one molex-to-6-Pin adapter?
