View Full Version : Cooler Master RS-450-ACLX ok?

10-08-2005, 07:54 PM
Wanted to pickup a PS today at Micro Center, don't want to spend $$$. Looking for a good PS at a good price I saw what seemed to be a couple options, a Cooler Master "Real Power 450" for $39.99 afer $30 rebate and some other brand I don't remember 400 watt for $29.99 after $10 reabate, but the $29 one has PFC, Cooler Master one doesn't have PFC ~ hmm... I saw on the display model Cooler Master that the price used to be $119, so I figured maybe $39.99 is a pretty good deal?

How important is PFC? I'm not going to be running SLI so 450 watts is plenty, but I don't want any PS related problems. Is there any other under $50 that might be better/more reliable/quieter? Or is this a pretty good deal, and maybe the this PS built solid enough to be trouble free for a couple years? So far I think my (other than non-PFC) only concern is how long a "rifle bearing" fan will last.

Complete system specs please.

The new XCillo 450W & Fortron 400w/450W would seem to be fine. :toast:

I got that power supply already, I think I'll keep it, unless I find out that it's crappy. I don't know yet how important "PFC" is. I would guess that how efficient a power supply is might roughly correspond with how cool it runs, how long it lasts, and how stable it is.

You asked for system specs, ok, so far:

Athlon 64 3000+ Venice 0517 DPMW running at 266Mhz/2.4Ghz
ASRock 939Dual-SATA2 MB memory set to "133" running at ~ 171 Mhz
2x 512 MB Centon PC3200 with Elixer chips (made by Nanya I think)
eVGA 6800 nu with all pipes & vertex units unlocked, slightly overclocked
Coolermaster RS-450-ACLX power supply
Antec "Premium" mid tower ATX case old solidly built heavy steel case
SoundBlaster Audigy 2 ZS Platinum Pro EX

Might put my ATi HDTV Wonder card in this system, not sure yet.

I didn't see anything called "HTT" in the BIOS settings, running std. factory 1.20 BIOS, default voltage on both CPU and memory. If I up the memory setting from "133" to "166" with the FSB increased to 266 from 200 the system won't boot. I'm not planing on going much higher than 266 but I would like a little higher speed on the memory. Thinking of getting an XP-90 HS, not really sure which HS to get yet though, would like to get good value, not going to go to Xtreme on this system for now I think, maybe I will later.

This power supply comes with a meter, so far the system stays under 100 Watts on the meter even when playing FPS game online, I don't imagine that could be accurate? It must be closer to 200 Watts, no?

Your max combined +12V is only 12V@22A: http://www.coolermaster.com/index.php?LT=english&Language_s=2&url_place=product&p_serial=RS-450-ACLX&other_title=+RS-450-ACLX+Real%20Power%20450

Probably "ok" with a 6800nu, but if you upgrade, you want a min of +12V@26A. :fact:

it will not cut it if you ever upgrade...
and you really shouldn't cheap out when it comes to one of the most vital parts of your system...
