[ssb1551]

coz couldn't find any Gigabyte PSU lower than 460W n thts for 2.2k!!

Guys need to buy a 350w power supply for a X4 based system without GPU, I was recommended FSP Saga II, but its not available here in Ahmedabad. Please recommend and alternative for about 1500Rs. Nothing more than that.

Please reply quickly. Thanks.

one possible option is Gigabyte 400W. forgotten the full name. but as FSP isn't available, i doubt you'll be able find Gigabyte. last option & least recommended is VIP Gold 400W.

[ssb1551]

^^tried to look in so many sites abt Giga 400W Sam but cudn't find it!!Hope OP is lucky to find at his place!!

VIP Gold 400W.

Scrap of metal. Avoid it should be!!! Same for newer silver ones/zebronics.

One PSU poll you might be interested in ....
Which True Power Supply Unit (SMPS) You Think is The Best Quality and at a Justified Price Tag?

^^ lol psu don't run based on popular choices . Can't afford a decent power supply for the system, you are bound to get a hard hit on your investment. Buying power supplies based on brand is simply stupid thing to do. You're not buying a pair of jeans, are you?

are iball , mercury etc cabinets with 450watts smps safe ?
can we install a graphic card with those smps ?
is there any risk ? is it safe ?

[ssb1551]

These PSUs are of sub standard quality. Not recommended to install a discrete GPU using these power supplies. Just that the ratings which are stamped on the units -- will not be delivered. Your system is at risk. The problem can propagate to other components, resulting in failure/burn out. Best to avoid. Hope this helps.

[sam]

in simple term: buy good PSU (mayn't be best, but at least safe) now or buy a new PSU + a new HDD + new pair of ram +.............. and the list continues.

get a new powersupply. Your current psu can't handle it. The comp guy is a fool trying to sell scrap metal. Get a good psu from reputed brands like corsair, gigabyte or fsp. A 450w psu with 80+ certification is a must.

Since u hv HD5670 u can get Corsair CX400W for 2.7k!

How good are Seasonic and Silverstone brands as for PSUs ?

even FSP Saga II 350W will do but that will close his upgrade path. he should get FSP Saga II 400W or Gigabyte Superb 460W. these are the bare minimum he should consider if he wants an open upgrade path.

Hey guys pardon me for this off track query but gotta ask. I am noticing for last two months that my electric usage unit has gone up by a high rate. Is my Cooler Master Extreme Power Plus 600W PSU a causing this? Coz last year in this time of year my meter unit was 300, in this year it is 580, in October. I have added no new gadgets from last year except the CM PSU and my desktop is on for same duration as last year. So I was thinking it might be my PSU. Oh, my last PSU was a e-life 500W.
If it's my PSU then does every high wattage PSU act same,including Corsair and others?
Electric bill is suddenly cozing me a problem as I am not a BILLIONAIRE. LOL.

maybe. all i can say is, efficiency went down, power consumption went up (by the PSU), so bill went up too.

no, all PSUs efficiency comes down but the good ones (Corsair, Seasonic) maintains their near perfect efficiency. so even after a yr or 2, your power consumption doesn't goes up. at least not significantly to reflect in electricity bills.

speaking of cheap PSUs or the ones you use, most even don't last to show their efficiency drop. only after a yr they go BOOM. warranty over, PSU over.

[ithehappy]

Hmm but a 3.8K PSU is not cheap to me at all and it's just a month old.

[sam]

^^ high price always doesn't means you getting good components. but if its a month old, than it maybe for some other problem also. i can't guarantee your PSU is culprit. but

I think this is an article worth a look: Who's Who In Power Supplies: Brands, Labels, And OEMs

aby geek already pointed it out here.

anyway thanks for the link.

While the quality of of some PSU is going down , a decent branded ones like Coolermaster , Seasonic , Cosair etc are far safer bet than 400Rs cheap PSU.
Imporant thing is to look for protection features like OCP , OVP ,
OPP , OTP , PFC etc.
Before buying PSU always check sites like
eXtreme Power Supply Calculator
For people with graphic card Amperage on 12V rail should addition consideration.
Many branded PSU 's actual Wattage is lower than whats written on PSU unit , so its good idea to buy higher atleast 30% higher Watt PSU than required.
My buying criteria.
A good 400W costs around 2500 rs (for entry level comp).
A 460W is good for low end HTPC graphic card.
For low-mid end graphic card ( 9800 GT or equivalent) a true 500W is safe choice.
Personally i am using CoolerMaster 460 W Exxtreme on Dual Core AMD with no graphic card and Cooler Master Real Power Pro with Intel Dual Core + 9600GT without any issue.

There s no way PSU is doing that. There are lots more power guzzler home appliances like Geysor , A.C , Fridge etc. You should check them first.
Another factor could be that new Electronic meters tends to run much faster when it has "Earth wire" related issue

[Piyush]

my gx 550W went kaput yesterday
the red wire in p11 p12 wire was burned badly

most probably i'll go for real power pro 460W
