Will my 320 watt PS handle a GTX 670 GPU?

[tweakboy]

Antec is superior in quality.

Also those GPUs the high end ones like a 670 takes up 300 watts when massively overclocked. CPU takes avg 220watt when OCed to 4.6Ghz and above


Buy a Thermaltake ToughPower mines been running strong for 5 years almost and most of time on.

These wattage is my opinion not to be taken as facts! But close enough numbers.

Antec doesn't even make their own PSUs, and they often skimp on things like the fan quality, capacitors (Chinese instead of Japanese), etc. Give me a break. And yes a massive overvolt + overclock will dramatically increase your wattage, but for more moderate overclocks you will be fine.

Are the OCZ modstream any good? They have the 600W for $50 AR right now at Newegg. I doubt I'll do huge over clocks, but I don't want to pick up a Capstone 450W and find myself short.

The Antec 520C should work but it's expensive for what you get. $47 shipped for that vs $60 shipped for the Rosewill Capstone 450W that is a known well-built PSU with massive 444W on the 12v rail and GOLD power efficiency should be a no-brainer in favor of the Capstone.

you get what you pay for....

With the GPUs you are looking for, the only way you'll possibly find yourself short is if you SLI/Crossfire and I'm not even sure you would be short even then.

The OCZ you asked about blows.

Get a clue dude. Antec uses quality OEMs in most of their PSUs. I've been using Antec and Enermax PSUs since 1998 in over 500 rigs and of those, it takes 3 to 4 years for them to fail in 24/7 operation. I can vouch for the Eco Neo 520c and 620c as well as the earthwatts line and the HCG series. All quality. Saying antec makes a sub par PSU just makes you look ignorant. They are some of the most reliable in the business.

To OP: If you get an antec PSU you'll be set. I've seen a 520 power 3 6950s using molex adapters pulling 600W from the wall. Skip this clown's rhetoric and go with a trusted brand.

Wait... You think failing after 3 years is impressive? Lol. You just convinced me never to consider Antec.

Not that I would anyway. The debacle with the low quality caps coupled with a fan profile that lets the PSU overheat before moving any amount air that plagued the TP and TPII series was enough for me to look at other brands from there on out.

1. Antec does not make their own PSUs. Yeah they usually don't pick the worst OEMs to resell PSUs from, but neither do they tell those OEMs to build top notch PSUs. See below.

2. Failing in 3-4 years is PATHETIC.

3. I never said Antec makes "subpar" PSUs; I was responding to the guy who claimed Antec PSUs were of "superior" quality. Superior to what, bottom-feeder PSUs? Midrange? High end? He didn't say and I definitely didn't want OP thinking Antec is top of the line. What I did say was this: Antec sells PSUs that often skimp on components. I am not impressed with their using Chinese caps and shaving off costs on fans and not even living up to their 80+ ratings in real life tests. Even in their higher-premium Plat line!

http://forums.pcpitstop.com/index.php?/topic/198642-antec-can-kiss-my/ (others have discovered that Antec's quality does not live up to their reputation and pricing)

http://www.jonnyguru.com/modules.php?name=NDArticles&op=Story2&ndar_id=8 (Antec has sold some rather poorly made PSUs before, sorry to burst your bubble)

4. Yes you can find some well-made PSUs sold under the Antec name, but they are priced at a premium that I don't think they deserve, given the alternatives available on the market. You could do worse than an Antec PSU usually, but they aren't selling the best-quality stuff. Too often they seem okay with their OEMs using Chinese caps and less-than-first-rate fans or controls.

I know, right? I'm lmao at this guy.

I have 2 Antec PSU's, a HCG 520W and a Signature 850W. HCG is a Seasonic made PSU, the Sig is a top notch PSU but at $299 MSRP, it better be.

Antec does sell some good stuff but there are too many variations in their lineup for my liking. Point being I can't make a broad statement like "Antec is great" because it really depends on the specific PSU. If you want consistent quality over entire lineup, look elsewhere.

I just had to register for this subject so that the poor OP or someone else having the same question could save some money - unless they already bought something. The HP Compaq Elite 8100 the OP refers to, is of special design. It will not accept any of your vanilla ATX dot whateverversion PSU's. The mobo physical power connectors are of some alien origins. The max wattage of PSU (of this type) HP delivers is 320W, the original one already installed. I got one of those myself and I also had the same problem. There are three possible solutions:

1) kick the beast back to where it came from and get another computer, of standard design this time

2) buy an auxilliary PSU feeding only the graphics card (no sense in SLI or CF in this case, the other PCI-E x16 is that by the physical connector only, the wiring is x4 only)

3) limit volutarily your selection of possible vidcards into ones without the need of a PCI-E power connector.

Personally I went 3), and bought a second hand XFX 9800GT Green. Another possibility along the path I chose, and probably a better one, would have been to purchase an Ati HD7750. They are currently the most powerful (gamewise, that is) cards without the need for a PCI-E power connector.
