9800GT work With this PSU

redryan89 · Sep 23, 2013

Hey Guys

I was wondering if anyone could help me out, i am building a PC for my partner (budgeted) to run World of Warcraft and i have a 9800GT but i am trying to pick out a power pack and a decent one at that because i have no clue how good rated power packs are but i have hear "Enermax" are a good brand.

http://www.ebay.co.uk/itm/Enermax-EG495AX-VE-485w-PSU-/271274878523?pt=UK_Computing_PowerSupplies_EH&hash=item3f293e263b

This is the powerpack i want to buy and i need help whether or not it's good enough, i am not doing any overclocking of any sort i am just building a budgeted pc to work decent enough for world of warcraft.

Hope you can give me some advice

Many Thanks
Ryan

Whoever you get your hears from, you need to stop listening to them. When it comes to power supplies (a power pack wouldn't have to be plugged in), Enermax is a HORRIBLE brand, and not remotely reliable.

Also, we can't tell you how much wattage you need without actually knowing more than one part - what else will be in the computer other than the 9800gt?

I don't have a lot of information at the current specs to the computer as i am still looking about but if the information helps i'm mainly looking for a decent PSU, i am going to be running a dual-core with a gaming case, approx 4-8gb of ram and 9800GT so that is the type of build im looking at when i get everything together, sorry that i couldn't be more specific.

If your budget is limited, just bag a used Thermaltake Toughpower 750W off eBay for
a good price. I've been doing this for years, saves a fortune and they're excellent PSUs.

750W is of course overkill, but it's the most common model to show up. However, atm
there's a 500W which would be ok. See item 231060357637.

If you do want to buy new, I know the CIT 750W Gold is ok. I built a dual-core AMD
setup for my neighbour a few years ago using one of these; 6000+ @ 3GHz, 4GB
RAM, 120GB SSD (recent upgrade from a 146GB 15K SCSI), 8800GT 512MB, 500GB
SATA, ASUS M3N board, etc. Been running fine no problems at all. See:

I would not however use a PSU of this kind if I was going to be doing any overclocking -
that's where used Toughpower units come in. 8)

PS. I agree with the previous reply, avoid Enermax.

Thanks for the information, i wasn't too sure how good CIT even though i've seen them many times, but yea as i said i won't be overclocking or anything to put pressure on the PSU, so thanks ian

i'll look into it later.

Enermax isn't horrible. Their budget series is Lepa, which is also quite good. One of the few who actually make their own PSUs, and oddly enough don't normally make them for others. They are often more expensive then other PSUs of similar quality which is why I don't normally use or suggest them.

9800GT? Card is rather old. It's not a high draw card so any of the normal PSUs will work. I would avoid running any of the suggested 750W PSUs as the efficiency would be really bad.

On the contrary, such PSUs work perfectly fine, and they will be more reliable which
is more important. If anything, low-W rated PSUs are usually less efficient because
they're cheaper constructions. Remember, a PC config isn't going to draw more power
from a PSU just because it has a higher rating.

Also means there's much more room for future expansion, eg. adding a modern GPU
which might otherwise stress a much lower rated PSU.

I completely disagree. A units wattage has nothing to do with how efficient it is. As a matter of fact I think today I'm finally moving from my Antec 750W green (bronze rated) to my new Capstone 450W (gold rated). Why would I do this? Efficiency. At gaming load my machine should be around 325W draw. This is just under 50% load for the 750. 80+ says I should be around 85%. Even if I was maxing out my gold unit, which I'm not, I'd be at 87%+. It gets better when you look at browsing or idle figures however. This is where I and probably most of us spend our time. At low(er) loads I should be drawing just over 100W, probably around 125-150 due to my hdd problem. At 150W I'm using 20% of my 750W which should be 82%. But the lower wattage 450W Gold will be using 33% and should be at 87%+ Slightly better at load, but much better at idle. And of course buying a 750W unit to run a 6300 and a 7850 is a joke as even at load you won't be near 50% of output.

adding a modern GPU which might otherwise stress a much lower rated PSU.

There is a huge difference between lower rated, and lower quality.
