Hi, guys just a quick question, i recently purchased a 500W PSU and a Asus Radeon 6770 graphics card for my computer.

I'm a bit paranoid, and don't know a lot about computers to be honest, i just want someone to confirm if this will install and work OK on my current machine.

This was the PSU i bought: http://www.amazon.co.uk/Evolved-Sumvision-500w-Power-Su...

And this was the card: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Here's a quick speccy of my machine. ignore my current GPU:

Operating System
MS Windows 7 Professional 64-bit SP1
CPU
Intel Pentium D 820
SmithField 90nm Technology
RAM
4.00 GB Dual-Channel DDR2 @ 402MHz (5-5-5-18)
Motherboard
ASRock G31M-VS2 (CPUSocket) 35 °C
Graphics
Dell E193FP (1280x1024@60Hz)
1024MB GeForce 9500 GT (XFX Pine Group) 62 °C
Hard Drives
233GB Western Digital WDC WD2500JS-22NCB1 ATA Device (SATA) 33 °C
Optical Drives
MagicISO Virtual DVD-ROM0000
HL-DT-ST DVD-RAM GH22LP20 ATA Device
Audio
Line 6 UX1

My current PSU on this is 300W max power but it's effectively 280W

Here's the motherboard in more detail (might be helpful):

it appears that both your psu and video card are compatible with the system..so everything would hook up and work but what you should worry about is if both the gpu and psu will physically fit in the case...if the psu in there is of a standard size your new one will fit fine and you just gotta make sure that your gpu will have enough room ...to find this out since you already have the products in your hand is to just try and toss them in there.

That PSU is terrible. It's rated for 14 amps on the 12V rail. That's a 250W PSU at best.

It may or may not work. It's risky IMO. I would recommend buying a quality 350-400W PSU from a reliable brand like Antec, Corsair, OCZ, Seasonic, or XFX.

Here's a review of that PSU:

http://www.expertreviews.co.uk/psus/118103/sumvision-po...

Quote:
At 50 per cent load, the Power X's voltages were witin the ATX specification. Average efficiency was the lowest in the group at 71 per cent. Once we increased the load to 75 per cent, the PSU ran for five seconds before exploding spectacularly.

The Power X is very cheap but can't even deliver 375W, let alone 500W. One to avoid.

^^problem is he already bought it lol....maybe he can return it but he only got a 6670 that should be fine for that gpu

How many amps on the 12V rail is the one you have now? That is an awful power supply.

At least you have a dual core though. :) 
August 31, 2012 4:41:02 PM

Lol, oh my god, how are they even allowed to sell a PSU as *** as this? I'm not too fussed, it was only just above £10 to be fair, i wasn't expecting to be able to power half of China. It should work with though, and what can happen if it doesn't work, destroy my whole system?

Here's my current PSU http://imageshack.us/f/225/psuf.jpg/
no idea what all this means.. i think it's 280 Max though..

Yeah, i already checked with the graphics card. Slots in fine, was major worried about that!

I think the power supply you have now is more fit to run that card than the one you just bought.

The 6670 doesn't have that much of a power draw.

Says 15 Amps on the 12V rail, 1 more than at Amazon. Anyway, it's still pretty terrible. It's probably enough to run your hardware, but with a cheap, low-quality PSU it's better to be very careful. If you push it, fireworks may go off in your computer and that can fry your other parts as well as the PSU.

yea man go for it. that current psu you have now should be able to handle it just fine

Actually, Yes if the PSU dies it can and usually will take other hardware with it, anywhere from a single piece of hardware to the entire system can be damaged when a PSU fails. Seen this happen way to many times with cheap power supplies, it's a costly lesson to NEVER skimp when it comes to buying a PSU.

Alright cheers, i'll fit it and tell you guys how i get on!

hopefully you can return the psu you bought if you got it already. good luck putting it in
August 31, 2012 8:23:43 PM

That's it fitted, how long until my computer explodes? Seems to work fine, is there any damage i can cause from doing this though, not running the graphics card with a high enough wattage? And yeah, thanks! i'll try and return it, i should be able to!

Again, the 6670 does not have that much of a power draw. You should be fine on 15a, but a new PSU would be nice.

The thing is, with these cheap PSUs you can't really trust the numbers they claim. I mean, the 500W number is ludicrous, so the 15A number could easily be fiction too. Though it seems a lot more realistic for a PSU in that price range than 500W.

I'm running the 6670 just now from the 280 old PSU and it seems to be working fine. Just a quick question though, if my PSU was a good 500W PSU, would there be a massive difference in performance, gaming/graphics wise? By massive i mean significantly massive?
August 31, 2012 9:45:40 PM

As i'm running guild wars 2 now, and it's really hard to play, even with the 6670, but from what i've read, it tells me that this card should cope with the game quite easily. Which leads to two things in my head, the graphics card isn't working properly due to the PSU, or my CPU's just too *** to run the game? I'm mostly drawn to the CPU conclusion as it is pretty bad, and i'm sure i've read about "bottlenecking" the GPU if the CPU isn't powerful enough to cope, although i know very little about computing to be quite honest.

No, not at all. It just reduces the risk of a crash or (worst case) a blown-up computer. Chances are you'll be fine with your old PSU. A 500W PSU would be a bit overkill for your machine.

The CPU definitely has something to do with that. The 6670 probably won't let you play with all the bells and whistles, but it should certainly be playable.
August 31, 2012 10:32:26 PM

Yeah, i'm planning on getting a more powerful CPU, i should definitely buy a more powerful PSU now though eh haha?

You can always just get a new PSU later. Maybe like when the funds come in.
August 31, 2012 10:43:40 PM

Doesn't a more powerful processor require a higher wattage of PSU?
a c 189 U Graphics card
August 31, 2012 10:45:35 PM

Not necessarily. I would upgrade them at the same time though.

generally only if the TDP of the processor is different or its overclocked

The max TDP on my current is 95W.

If i buy a new CPU and the max TDP is higher, i need a more powerful PSU?
a c 107 U Graphics card

I cant say much, because experiences may differ. a higher tdp just means it will more likely consume more power. if that power is still within psu limits is a question that cannot be 100% answered as of the moment.

You'll probably need a new PSU anyway.

Ivy Bridge Core i5 CPUs have a TDP of 77W, so at stock clocks they probably use a little less power than your Pentium.

Yeah, it was just an example if you upgraded to a brand-new motherboard, CPU etc.
Your current PSU could still be good enough then.
