PSU Dilemma to use with APC UPS

**Infected** · 06-07-08, 03:11 AM

Hi

I'm looking forward to upgrading my SMPS. I really wanted the Corsair HX 520 but it has issues with my APC back-UPS RS 800 because of active PFC and simulated sine wave from the UPS. Can you guys please recommend me a good modular PSU between 500-600 Watts that does not have an issue with my UPS?

Thanks for your help

Have a nice day

Ritesh

HX520 aint avl in India. Other modular is HX620 which too has issues. TX650 seems good alternative, U can always throw useless cables in corner. or Tagan 700W or above. and CM Real Power/Green Power etc have also modular SMPS.

Does CM Real Power/Green Power etc have any issues with APC Back-UPS 800?

^^ I am using CM 600 Extreme + APC 650VA with no problem at all.

TX750W has issues too and TX650 might have them as well. Actually any thing with Active PFCs will present with problems.

If it gets fixed I will get a CM 600 or the vx series of corsair.

Do not get the CM600. It has deltas upto .8V on the 12V rail, on most pieces, which are excessive and well out of spec. Also it is very very noisy.

**Infected** · 07-07-08, 07:59 PM

..ok now I am having real issues.

First I wanted a new SMPS as this one is about 5 years old!!!

I couldnt decide on a SMPS and now APC too gives me things to spend on!!! :-(

^^If you want i can sell my CM600W(2 months old) for 2.5k as i want to upgrade to 700W SMPS.

**tangentray** · 07-07-08, 10:38 PM

Call ur local apc dealer and get a new battery, i guess it would cost you around 1k at most.

**tangentray** · 07-07-08, 10:38 PM

Most people who have a CM Extreme power 600 want to get rid of it.

Maybe get a VX450 or something better instead.

The UPS battery costs ~700 bucks.... change your battery first & see if the problem persists... if it does then only change the SMPS....

**Infected** · 08-07-08, 06:21 PM

"if it does then only change the SMPS...." I wanted to change it anyway as this is almost 4 years old.

The APC died by chance..has nothing to do with the starting of this thread.
