Is this PSU suitable?

[Giantwasp]

I am planning on getting AeroPower II+SE 550W as not many seem to have heard of this one these are the specs:
- ATX 12V Version 1.3
- Electric Shock Protection
- Scan-Disc-Free Protection (PS_Off # >2ms)
- Over Voltage Protection
- Over Current Protection
- Short Circuit Protection
- Stable Regulation for +5V, +3.3V, +12V at +/- 5%
- AUTO ranging Active PFC at 0.989
- Dual Blue LED fan design ( front and rear ) with 3 year warranty
- APS-HD Technology : Asynchronous Protection System for heat dissipation
- OVP/ OCP / SCP on all 6 DC Output Rails

I know someone is going to say that I should get an Antec but I like the blue light and the fact that it is alledgedly "super silent". I know that is silly and I will go for something else if it will put my system at risk.
I did read a good review of it somewhere.

Here is the rest of my proposed setup; is this PSU suitable and is there any other parts you think I should change?

Monitors - 2 x Dell 1900FP (Have)
Case - Lian-Li v1100 (Bought)
HDDs - 2 x WD 120GB 7200rmp 8mb, in RAID 1 (not SATA because have one already)
GPU - Asus Geforce 6800Ultra or Point of View 6800 Ultra
CPU - AMD Athlon64 3500+ (Bought)
Motherboard - Asus A8V Deluxe Wireless edition
RAM - 1GB OCZ (2x512MB) PC3700 Dual Channel Platinum Edition EB-DDR CAS3
HSF - Zalman CNPS7000B-Cu
FDD - Value Floppy Drive, Silver
Optical drive - Sony DWU-18A 8x DVD±RW ReWriter (Silver)
Game Pad -BELKIN Nostromo SpeedPad n52
Keyboard - Coolermaster Q
Mouse - Logitec Optical (Have)

All running Linux Fedora Core 2 not Windows!

I would very highly recommend the Seasonic Super Silencer 460W. Its extremely stable, has a very high efficiency rating (over 80%), and is one of the (if not the) most quiet >450W PSU on the market.

Most people overshoot their PSU power requirements. This is based in part to ignorance (not sure, so better safe than sorry), and the fact that cheap power supplies often give highly inflated power ratings - making people think they need more power than they actually do. The Seasonic will be perfectly stable at 100% maximum power output, unlike most PSUs on the market. However I seriously doubt you'll reach that level though. 460W of real power is more than enough for what you have.

There are other equally capable PSUs on the market, but none at that power level that are quite as quiet as the Seasonic.

Thats just my two cents.

I thought the geforce 6800 Ultra needed 480W?

Another big problem with the Seasonic is that it does not appear to be available in the UK

If that card needs 480W, then you should run the other way screaming. 480W is like having 4 prescott processors on full boil inside your case. No desktop system puts out that much heat. Even if that GPU uses 100W (which I doubt it does), then your system might only draw a maximum of 300W if everything was going full blast at once.

I think the 480W figure comes from a "worst case" scenario in which the end uses buys some mid-low grade power supply. A PSU with a stable, true 460W output will more than suffice for your specific needs.


But if the Seasonic isnt available to you in the UK, then I guess its a moot point. Good luck finding something.

I know very little about PSU but I am basing the 480W requirement on pretty much all the manufacturers requirements for the ultra cards. And also people on this forum planning to buy a new PSU to run an Ultra card.

I can well understand that a good PSU does not need to be as powerful as a cheap one though.
