Q6600 and 7800GTX on bundled Chieftec 400W?

post #1 of 6
Thread Starter 
Hi all, sorry if a similar thread has been posted but I searched and didn't see one.

I recently bought a PC with a pentium D and a 7800GTX running on a Chieftec GPS-400AA-101 A 400W PSU and I'm wondering if it's capable of powering a different PC in my house in the long term.

I've looked up a couple of things already and the 12V might be cutting it quite close for what I have in mind.

It's rated to supply 348W on the 12V rail and according to this review it can be trusted to do that.

My question is, could I trust this PSU to run the following PC in the long term?

CPU: Q6600 OC'd to 3.6 (184W according to this calculator.)
Mobo: Asus P5Q-e. Guessing 25W but I don't know.
Graphics card: 7800GTX. ~85W
RAM: 2x1GB ballistix and 2x1GB generic 1066 running at 800 CL4 ~20W?
HDD: Single seagate 250GB 7200RPM. ~10W
Fans: 1 80mm and 4x 120mm totalling 13W


So the theoretical max going by my potentially inaccurate figures is 337W.

Would I be safe in assuming it's not going to come near that in practice and that this PSU will do fine?

Also if it will handle the load, will the ripple be an issue?
It looks like about 80mV of ripple on the 12V rail and pretty close to the maximum allowable on the 3.3V and 5V according to that review, could anyone tell me how that would affect the stability or expected lifespan of the components?

The back-story behind this is I lent my parents my HX620 for their PC and it looks like it's going to stay lent as they aren't exactly rushing out to buy a new one.
I want to know if the chieftec PSU will do because, if at some point I need a decent PSU for another build, I'd like to be able to swap it for the HX without buying a new PSU.

I'm guessing it would probably run fine but it's too close for me to risk it, I just said I'd get a second opinion before I try it.

Anyway I'll shut up now, any input is appreciated so feel free to jump in with your opinion.

A decent 400W PSU will easily run that system, a 350W would most likely be more than adequate

Thanks, but I'm mostly just wondering if the ripple will affect my components in some way and if this PSU, which looks to be a few years old, could handle the PC now.
I'm also looking to find out more about this PSU in general.
I know it's made by delta and that it shipped with chieftec cases.
I found that one roundup that mentioned it but other than that I can't find much info about it.

I also know a good 350W unit would handle it, I was just wondering if this particular PSU was trustworthy?

Edit: *Finds a post by Phaedrus to click the link in his sig and educate himself*
Not worried about the ripple anymore as it's probably fine but if someone wants to come in here and tell me the PSU is a time-bomb I won't object
I'm guessing it's okay so I'll install it tomorrow

As long as it is within spec, there won't be any damage. The ripple on the 3.3V and 5V won't be that significant, as in real life usage those rails will never be loaded to the maximum. I've had some Chieftec cases with that same PSU bundled, and used them without issues. As far as bundled PSUs go, these are actually some of the better ones.
